A variety of recent theoretical and empirical advances have renewed interest in monopsonistic models of the labor market. However, there is little direct empirical support for these models, even in labor markets that are textbook examples of monopsony. We use an exogenous change in wages at...

This article introduces a new approach for evaluating the quality of healthcare providers, including an integrated solution to several problems that limit the usefulness of available methods. Our approach combines information from all the quality indicators available for a provider (e.g., from...

This paper develops asymptotic distribution theory for instrumental variables regression when the partial correlations between the instruments and the endogenous variables are weak, here modeled as local to zero. Asymptotic representation are provided for various statistics, including two-stage...

In his classic 1957 study of hybrid corn, Griliches emphasized the importance of economic incentives and profitability in the adoption of new technology, and this focus has been continued in the economics literature. But there is a distinct literature with roots in sociology emphasizing the...

The authors investigate the effect of abortion access on teen birthrates using county-level panel data. Past research suggested that prohibiting abortion led to higher teen birthrates. Perhaps surprisingly, the authors find that more recent restrictions in abortion access, including the closing...

Theory suggests that abortion restrictions will influence fertility outcomes such as pregnancy, abortion, and birth. This paper exploits the variations in abortion policy generated in Eastern Europe in the late 1980s and early 1990s to examine their impact on fertility outcomes. We distinguish...

We examine the impact of increased abortion availability on the average living standards of children through a selection effect. Would the marginal child who was not born have grown up in different circumstances than the average child? We use variation in the timing of abortion legalization...

Abortion legalization in the early 1970s led to dramatic changes in fertility. Some research has suggested that it altered cohort outcomes, but this literature has been limited and controversial. In this paper, we provide a framework for understanding selection mechanisms and use that framework...
